Title: Device for wire bonding
Inventor: KAMIJIYOU ATSUSHI
IPC: H01L21/60
Filed: 1982-11-24
Abstract: PURPOSE:To enable to perform a stabilzed ball formation in an air stream of inert gas by a method wherein a plurality of nozzles connected to a stage are provided in the vicinity of the part which will be turned to ball-like shape at the tip of the metal thin wire which will be led out from a capillary. CONSTITUTION:A plurality of nozzles 7 connected to a stage are provided in the vicinity of the part which will be turned to ball-like shape by electric discharge at the tip of the metal thin wire led out from a capillary 2. As nitrogen or inert gas is blown from a plurality of directions pinching an opposed pole 4 for electric torch, the effect of a cross wind can be prevented substantially when a ballup is performed, and a stabilized ballup formation can be performed. Besides, the atmosphere at the ball forming position can be made more completely when compared with the case where nitrogen or inert gas is blown from one direction only. As a result, the oxidation of impurities added to the wire 3 and the precipitation of oxide can be prevented. Also, a reliable wire connection can be performed on the wire such as a silver wire which is easily oxidized.

Title: Motor and motor-incorporated equipment
Inventor: KOBAYASHI MASAMI
IPC: G02B26/10
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To reduce or prevent vibration being generated by the thermal expansion of each part when a motor rotates by providing a means for diffusing the air between a sleeve and a case due to the rotation of the sleeve at the end part of the sleeve that is inserted into a rotary shaft so that it can be freely rotated and acts as a bearing. SOLUTION: A ring 15 for correcting balance is fixed at the lower end part of a sleeve 6 by caulking. The ring 15 for correcting balance is fixed to the sleeve 6 by caulking to prevent the fixed ring from being loosened or falling off when the sleeve 6 is thermally expanded. Therefore, it is inappropriate that the ring is fixed by gluing. The ring 15 for correcting balance is in a polygonal shape so that air is diffused on the side surface on rotation. The ring 15 for correcting balance uses a member with a thermal coefficient of expansion that is smaller than that of the sleeve (for example, aluminum). When the thickness of the ring 15 for correcting balance is approximately 2 mm or more, the thicker the ring is, the more effectively air is diffused.

Inventor: PFEIFFER THOMAS DR
IPC: H04J13/00
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To suppress side-to-side crosstalk by evaluating an input signal to be modulated on the side of a transmitter or receiver corresponding to the jitter impressed to the carrier frequency of a frequency deviation comb assembly or jitter in the frequency gap of frequency deviation comb assembly. SOLUTION: A signal 1 is inputted through an optical filter to a microwave oscillator 7, and the optical output of an optical filter 3 is inputted through a photodetector 4 to an amplifier 5. The output signal of the amplifier 5 is transmitted to a microwave detector 6, a sub carrier signal is converted again and electric output data can be utilized again. The modulation of the optical filter 3 is performed by an optical phase modulator. The frequency deviation comb assembly for transfer depends on the jitter. Thus, the optical transmission signal is affected and an electric signal can be evaluated on the side of reception while using the microwave detector 6. Therefore, the carrier frequency of the frequency deviation comb assembly is modulated or spectrum range of a transmitter filter is modulated on the side of a transmitter and the jitter can be prepared.

Title: Drive control system for printer
Inventor: SUN ESU CHIYAN
IPC: G07B17/00
Filed: 1988-08-19
Abstract: PURPOSE: To improve system throughput of a postage meter mailing machine without giving bad influence to wearing characteristics of a system by operating a meter drum at a slower speed than the mail output speed of a feed means. CONSTITUTION: When a mailing machine 10 receives an envelope 16 from a feed means 14, a microcomputor operates the speed of the incoming envelope 16 to select a definite through-speed to a printing drum 32 being made a little slower than the speed of the incoming mail. When the apex of the envelope 16 passes through a trip sensor 71, the speed of a transport system 20 is decreased to make the speed of the envelope 16 equal to the definite 'through- speed' of the circumference of the printing drum 32 during printing. When printing is finished, there exists no possibility of bringing the mail matter 16 into contact with the printing drum 32 and the microcomputor accelerates the transport system 23 from the 'through-speed' of the drum to a faster IN-SPEED and the speed of a meter drum is simultaneously decreased from the 'through- speed' to zero speed. Fast acceleration of the transport system prepares to receive the next mail matter at a synchronuous speed.

Title: Measuring apparatus for outside diameter of steel pipe
Inventor: KOMINE ISAMU
IPC: G01B11/08
Filed: 1981-12-23
Abstract: PURPOSE:To measure the outside diameter of a steel pipe in an on-line manner, by providing an outside-diameter measuring apparatus with a screw mechanism having thread parts different in pitch for moving phtodetectors disposed opposite to a projector in opposite directions according to the diameter of a steel pipe to be measured. CONSTITUTION:The pitch of a thread part 11 for moving one detector 2a is made large, while the pitch of a thread part 12 for moving the other detector 2b  is made small, and the thread parts are opposite in thread direction to each other. If the projection angle of light from a projector 1 is theta with respect to a fixing rest 5 and the radius of a steel pipe X is (r), the distances between the positions where the detectors 2a and 2b are set in measuring the steel pipe outside diameter on one hand and a reference line alpha on the other are represented by (1+costheta)r and (1-costheta)r, respectively. Therefore, if a ball screw 10 is employed having the thread parts 11, 12 with a pitch ratio of (1+costheta):(1-costheta), it is possible to set the detectors 2a, 2b at their respective predetermined reference positions by means of a single driver 4 at all times even if the diameter of the steel pipe X to be measured changes and the central position thereof changes.

Title: Infrared image pickup device
Inventor: MATSUDA TORU
IPC: G01J1/02
Filed: 1993-07-29
Abstract: PURPOSE:To interrupt heat radiation from a lens barrel, etc., so as to obtain excellent infrared images by providing a light interrupting means at a conjugate position with an aperture stop through an image forming means and relay lens group. CONSTITUTION:A spider 14 is provided near an aperture stop 2 and, in order to interrupt heat radiation from a lens barrel 4, etc., a light interrupting means 16 is provided. Since an optical system 1 is a reflecting optical system provided with a abberation correcting system and, in addition, a secondary image forming system for again forming the image of an object on a primary image forming surface 10 on an image pickup surface 6, the light emitted from the position of the stop 2 is condensed at a conjugate position 3 through a image forming means and a relay lens group 11. Accordingly, heat radiation from the spider 14 is condensed to the position 3 and forms a reduced image. Therefore, the arrival of the heat radiation from the spider 14 at an image pickup element 7 is prevented by using the light interrupting means 16 having a light interrupting extent similar to the image of the spider 14 formed at the position 3. Thus most of ghosts caused by unnecessary heat radiation other than the photographing light are eliminated while a cold shield 5 is prevented from becoming larger in size.

Title: Thermal transfer printer
Inventor: CHIN KOUEI
IPC: B41J13/22
Filed: 1993-07-29
Abstract: PURPOSE:To provide a thermal transfer printer which is low in cost, does not generate jam, and can print at a high speed with excellent precision. CONSTITUTION:A clamper 25 is attached to an end of a swing arm 13. When the clamper 25 clamps an image receiving paper 3, the swing arm 13 rotates from a stop pin 22 to a stop pin 23 by interlocking a platen roller 2 and stops at the stop pin 23. After printing in a single color is completed, the platen roller 2 is rotated reversely and the image receiving paper 3 is retracted from the back end. Accordingly, the image receiving paper 3 pulls the clamper 25, so that the swing arm 13 rotates until the stop pin 22 by keeping the image receiving paper 3 clamped. By repeating this process, printing is carried out sequentially so as to print in full color.

IPC: G02B7/10
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To reduce backlash and to decrease the time delay until the operation of a lens group by adjusting the frictional force of a transferring force limiting means at the time of driving an optical device by using a power transmission mechanism. SOLUTION: A friction plates 39, 40 are mutually oppositely provided between an operation ring 33 and an output cylinder 38, the friction plate 40 is movable to the output cylinder 38 in the direction of optical axis, restricted in the rotational direction and supported by a supporting plate 41 integrally rotated with the output cylinder 38. A transferring force limiting means is constituted so as to be slipped between the friction plates 39 and 40 against a load torque larger than a prescribed load torque. In this case, the prescribed friction torque is generated by adjusting the length of a spring 42. By rotating an operation ring 33 at the time of manual operation, since the friction plate 40 is slipped against the friction plate 39, driving force transferred from the operation ring 33 to the driving means is limited.

Abstract: PURPOSE:To improve operability with an easy reading of results of indication by outputting number or single weight as set through a proper display section among a piece-number display and a single weight display with the switching of a circuit according to an operation mode. CONSTITUTION:With the operation of a single weight setting key 20, an output is inverted to H and held while a gate 21 for switching a display data over to a single display 14 turns on a gate 22 under the operation of the single weight setting key 20 and a single weight written into a key-in register 5 through a ten-numeric key 6 is indicated on a single weight display 14 through the gates 22 and 24. With the operation of single weight setting key 20, a switching signal of a gate circuit 16 goes to H through an OR gate 25 so that an output of a subtractor 3 is supplied to a number display 15 through gates 17 and 19. Thus, as gates 16 and 21 are switched by the operation of the single weight setting key 20, in the second operation mode, data being keyed-in is indicated on the signal weight display 14 thereby facilitating the reading of results of the indication.

Inventor: YOSHIKUNI YUUZOU
IPC: H01S5/00
Filed: 1983-11-07
Abstract: PURPOSE:To improve the yield of a semiconductor laser and to enable to apply an FM modulation by the variation in the length of a waveguide by controlling a current applied to a control electrode formed above a photowaveguide, thereby varying the refractive index of the photowaveguide. CONSTITUTION:DFB lasers 1-5 are formed, and a laser operation is performed by injecting a current from a main electrode 5. A photowaveguide is formed with a composition having a band gap larger than an active layer 2, and coupled with the laser at the cleaved surface 7 in low loss. Carrier is injected by a current from a control electrode 8 to the photowaveguide 6, and the refractive index is varied by the current through the variation in the carrier density. Accordingly, the optical length of the photowaveguide 6 is varied by the current of the electrode 8, and the phase of the reflected light is varied. Thus, precise adjustment of the phase of the reflected surface can be performed to reliably obtain a stable single longitudinal mode oscillation by the adjustment of the current and to improve the yield. Further, a frequency modulation due to the variation in the control current can be performed.
